IMPROVEMENT IN CONDNSRS FOR CARDlNG-MACHINES.

Specification forming part of Letters Patent No.143,020, dated September 23, 1873; application filed March 25, w13.

.To all whom it may concern:

Be it known that I, NOAH LUCAS, of Norwich, New London county, Connecticut, have Invented a certain Improved Condenser for W'oolen Cards, of which the following is a specification My invention consists in the construction and arrangement upon the finishing-card of a series of like pairs of revolving disks, the whole series being secured upon a fixed rod running parallel with the doii'er of the card, there being one pair of disks secured in a vertical position in front of each ring on the doffer to condense the sliver from the stripper, each disk of the pair of disks revolving in opposite directions upon a separate shaft secured in each ofthe vertical sides of a wedgeshaped guide, which is secured upon said fixed rod, the faces of the disks thus converging nearly together, the object being to provide a more simple and effective substitute for the seven roll-condensers and tube-condensers now used, and one which will run lighter, entirely free from noise and jars, and, while doing better work, will be of greater durability.

Figure l is a horizontal section through the center of one pair of disks, and through their guide in the line s s, Fig. 2. Fig. 2 is a vertical section through the center of the guide between the disks in the line s s, Fig. 1.

A A are the circular disks, having whirls a a upon their outer sides, by which they receive motion in opposite directions from an ordinary drivin g-cylinder below-one by a straight, the other by a cross, belt. Their inner faces are preferably made smooth, with two concentric flanges, e e, raised upon them, the inner flange being higher than the outer, between which a washer, E, of leather, rubber, or other suitable material is pressed in, leaving the face of the washer iush above the top of the outer ange. B B are the shafts of the disks secured in the vertical sides of the converging guide C.' This guide has these vertical sides nearly meeting in front, so as to bring the front of the disks nearly together, while these sides, diverging at a small angle, enlarge into the hub K, by which the guide is secured upon the xed rod D by the set-screw d. The top of this guide C has a converging groove cut into it down to the center of the shafts B B, leaving a wall, c, standing upon each edge of the top of the guide, between which the sliver S S is guided'through, as shown in Fig. l, Without touching the revolving disks until it reaches the vertex of their angle, where it is condensed into roving. That portion of the guide and of each wall which is adjacent to the shafts B B is formed into a circular shoulder about the shafts, exactly filling the inner flange upon the face of the revolving disks A A.

When in operation the opposite motions of the condensing-disks A A by their pressure and friction against the sliver S S twist it back to the doffer-stripper and give it the proper tenacity to be drawn through the converging grooved guide C and between the faces ofthe condensing-disks, where it is condensed into roving for spinning. The proper draft is given to the roving by the ordinary drawing-rollers now used with tube-condensers.

I claim as my invention- The combination. and arrangement of vertical disks, the face of one revolving in an op-v posite direction to the other, their two faces forming an acute angle, between which the sliver is guided, to the vertex ofthe angle, where it is condensed into roving for spinning, substantially as herein set forth.

- NOAH LUCAS.
